must be pointing down. (See Figure 1)
Figure 1
4. Thread the 1-1/2" NPT pipe (C) into the ceiling plate and
tighten securely.
WARNING: Installations using a column longer than 24
inches require the use of a CMA340 Support Cable
accessory.
5. Secure NPT pipe to ceiling plate using one 5/16-18x3/8" set
screw (I).
6. Attach RPA to projector arm (A) using four 1/4-20 X 1-1/2"
carriage bolts (H), four 1/4-20 acorn nuts (G) and 1/4" flat
washers (J). (See Figure 2)
Figure 2
7. Slide both projector arms (A) onto the 1-1/2" vertical pipe
section and secure using two 5/16-18 x 3/8" set screws (I)
